Make your Dell 9T540 battery last longer:

1. Should I totally discharge and recharge my Dell 9T540 battery occasionally to make it last longer?

2. How do I get the most runtime for a charge?
   A: It is important to choose settings which allow you to obtain the most runtime from your notebook. Examples to consider: timeout settings for the hard drive, Bluetooth, wireless, LCD brightness, etc.
